Operating Manual CE-65-MELECTRONIC GmbH1 Safety1.1 General Potential for DangerThe CE-65-M rotary encoder cannot function as a stand-alone unit, i.e. it is a componentpart that is intended to be installed in a complete system consisting of severalsuch components working together. This means that the rotary encoder does not havea direct protection device of its own.Using the transfer log, the system can, however, output an error bit that shows an errorin internal data transfer or that a parameter was assigned an illegal value. To resetthe error bit, the error must be acknowledged. It is therefore crucial to integrate the errorbit into your own safety concept, via the evaluation software (e.g. of a PLC).(For more information, refer to section 1.6, Protective Devices on page 10).The encoder provides no diagnostics for errors that may occur, such as speed toohigh, track errors, transfer errors, etc. This means that you must check the receiveddata yourself for validity.All the persons who are involved in the assembly, commissioning and operation of thedevice• must be appropriately qualified• must follow exactly the instructions in this manual.This is for your own safety and the safety of your equipment!1.2 Safety InformationThis operating manual contains information that you must comply with to ensure yourpersonal safety and to avoid damage to property. The information is emphasized bywarning triangles, which have different appearances to match the level of danger:WarningMeans that if the appropriate safety measures are ignored, death, severe injury orconsiderable damage to property can occur.iCautionMeans that if the appropriate safety measures are ignored, slight injury or damage toproperty can occur.NoteEmphasizes important information about the product, its properties or helpful hints forusing it.TR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 10.10.1997 TR - ECE - BA - GB - 0007 - 02 Page 5 of 29

Operating Manual CE-65-MELECTRONIC GmbH1.2.1 Installation InformationDue to the fact that the rotary encoder is normally used as a component part of alarger system, this information is intended to provide a guideline for safe installationof the rotary encoder in its environment.Warning• Observe the safety and accident prevention regulations that apply to the specificapplication.• In the case of equipment with a fixed connection (stationary installations/systems)without allpole mains switches and/or fuses, you must install a mains switch or afuse in the system and connect the equipment to a protective earth.• Before commissioning devices that are run with mains voltage, check whether theset rated voltage range matches the local mains voltage.• With a 24-V supply, ensure safe electrical isolation of the extra-low voltage. Useonly mains units that comply with IEC 364-4-41 or HD 384.04.41 (VDE 0100 Part410) standards.• Fluctuations in or deviations from the rated mains voltage may not exceed the tolerancesstated in the technical data. If they do, functional failures of the electricalcomponents and hazardous conditions cannot be ruled out.• You must take precautions to ensure that, following voltage dips and failures, it ispossible to restart an interrupted program in an orderly manner. In this context, nodangerous operating status conditions may occure even for a brief period of time.If necessary, you must force an EMERGENCY STOP.• EMERGENCY STOP devices that comply with EN 60204/IEC 204 (VDE 0113)must remain effective in all the operating modes of the automation equipment.Unlocking the EMERGENCY STOP devices must not result in an uncontrolled orundefined restart.• Install the connecting and signal lines such that inductive and capacitive interferencedoes not adversely affect the automation functions.• Install automation technology equipment and its operator input elements such thatthey are sufficiently protected against being operated by mistake.• Take appropriate hardware and software measures in the I/O link to prevent possiblecable or wire breakages on the signal side leading to undefined status conditionsin the automation equipment.TR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 10.10.1997 TR - ECE - BA - GB - 0007 - 02 Page 6 of 29

Operating Manual CE-65-MELECTRONIC GmbH1.3 Appropriate UseThe rotary encoder is used to acquire angular motions as well as to condition measuringdata for a controller on the output side which has a DIN 19258-standardINTERBUS-S field bus interface. In addition, the rotary encoder has an SSI data interfaceto allow synchronous-serial transfer of angular data.The CE-65-M absolute encoder with INTERBUS-S interface is designed as a remotebus module with 32 I/O data. As a result, the device is integrated in the bus ring in thesame way as with a PHOENIX-CONTACT bus terminal and the system also processesit as such.WarningDeenergize the system before carrying out wiring or opening and closing electricalconnections!Short-circuits, voltage peaks etc. can lead to malfunctions and uncontrolled conditionsin the system or to serious personal injury or damage to property.Before switching on the system, check all the electrical connections!Connections that are made incorrectly can lead to system malfunctions; wrong connectionsmay result in serious personal injury or damage to property.For safety reasons, mechanical or electrical changes to the measuring systemsare prohibited!Caution*Avoid excessive bearing loadings due to radial and axial deviations betweenthe encoder and the drive shaft!At assembly, you must use couplings that can take up these forces.*Protect the encoder from excessive vibrations, shocks and jolts, e.g. onpresses!Use "shock modules“ to cushion vibrations.iNoteAlways keep to the commissioning, operating and programming instructions specifiedin this manual.* Observe the mechanical characteristics on page 13.TR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 10.10.1997 TR - ECE - BA - GB - 0007 - 02 Page 8 of 29

Operating Manual CE-65-MELECTRONIC GmbH2.4 Commissioning (Rotary Encoder)2.4.1 Encoder Interface (INTERBUS-S)The CE-65-M absolute encoder with INTERBUS-S interface is designed as a remotebus module with 32 I/O data. This makes it easy to integrate in the bus ring in thesame way as a PHOENIX-CONTACT bus terminal. To ensure that the protocol meetsINTERBUS-S requirements, an SYPI (serial microprocessor interface) is integratedbetween the CE-65-M absolute encoder and the INTERBUS-S. The SYPI is anINTERBUS-S protocol chip developed by PHOENIX-CONTACT which carries out thefollowing functions:• BUS interfacing: Directions of reception and transmission• CRC check• Preset• Transfer protocoletc.iNoteAt programming, data is exchanged between the encoder and the master in binaryform.TR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 10.10.1997 TR - ECE - BA - GB - 0007 - 02 Page 17 of 29

Operating Manual CE-65-MELECTRONIC GmbH2.4.1.1 Mapping of Encoder Data in the Master (Controller)In the master, the encoder data occupies two-word addresses for IN-data and twowordaddresses for OUT-data. The position of the data in the controller depends onthe physical or logical position of the encoder within the ring. For detailed information,refer to the manual of the master (controller) used.

Operating Manual CE-65-MELECTRONIC GmbHMeaning of the OUT-Data (Data from the Master to the Encoder)Normal Mode:Service bit 2 31 is set to “0“.OUT-data that the master outputs to the encoder does not have any effect and theencoder does not accept it.As a result, in normal mode the encoder only outputs its current position data.Service Mode:Service bit 2 31 is set to “1“.The encoder carries out the master's requested service (e.g. write direction of rotationor read programmed direction of rotation).The system evaluates or ignores the remaining OUT-data 2 23 to 2 0 in dependence onthe requested service.Bit 2 31 : Service bit 0 = Normal mode1 = Service modeBit 2 30 : Read-write bit 0 = Read data1 = Write dataBit 2 29 : Error bit 1 = ErrorBit 2 28 : Reserve Always 0Bit 2 27 to bit 2 24 : ServiceBit 2 23 to bit 2 0 : Data for service if bit 2 30 = 1,otherwise meaninglessMeaning of the IN-Data (Data from the Encoder to the Master)Normal Mode:The encoder outputs the current position data and writes it to bits 2 23 to 2 0 . Bits 2 31 to2 24 are “0“ unless there is an error; in this case, error bit 2 29 = “1“.Service Mode:If the master writes data (read-write bit = 1), the system returns the OUT-data to theIN-data (bits 2 31 to 2 0 ).If the master reads data (read-write bit = 0), bits 2 23 to 2 0 contain the requested dataand bits 2 31 to 2 24 contain the acknowledgement of the requested service.If the system could not carry out the service without errors, the error bit is “0“. It isonly possible to clear a set error bit by carrying out a data check service.TR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 10.10.1997 TR - ECE - BA - GB - 0007 - 02 Page 19 of 29

The host is in normal mode, service bit 2 31 is 0.The IN-data contains the encoder's actual position.2. The host outputs the data and the service number and sets the service bit to 1.Note:To guarantee data consistency between the commissioning card and the PLC, thedata and the service number must be output first. One PLC cycle later, the servicebit must be set from 0 to 1.With a read service, OUT data 2 23 to 2 0 is meaningless.3. The encoder detects and processes the service request, provides the appropriatedata and reports back to the host system by setting service bit 2 31 . With a readservice, the system returns the OUT data to the IN data.4. The host system detects execution and ends the service request.The system resets service bit 2 31 and switches back to normal mode.5.

Operating Manual CE-65-MELECTRONIC GmbH3.2.6 SSI-OUT Data InterfaceData TransferAt rest, Data+ and Clock+ are +5V (High). Data transfer starts with the MSB and isinitiated by the first falling clock edge. Data is changed by a positive clock edge. Dependingon the receiver, data is accepted with a rising or a falling edge.When the clock sequence is over, the system keeps the data lines at 0V (Low) for theduration of the mono period, t M . Time t M is set to 20 µs and it determines the lowesttransfer frequency of approximately 50 kHz. The upper limit frequency results fromthe total of all the signal propagation delays and is approximately 1.1 MHz.3.2.6.1 SSI Characteristic Values – Service 0D HexReading and writing are possible.Number of Data BitsUsing this parameter, you can shift data anywhere within the number of clock pulses.The data can be transferred right- or left-justified and with or without leading zeros.You generate leading zeros by generating a higher number of data bits than wouldnormally be necessary for the encoder.Value range: 08 to 20 HexNote (valid starting CW 41 / 97)By programming the number of data bits to 31 (1F hex) the SSI-output format will beset automatic to the AK-40 data format:31 data bits; binary; data bit 32 = Parity oddCodeThe code is a method for forming digital numbers. A code word is a bit pattern thatexpresses a numerical value. The code describes the assignments of code words andtheir values.In the case of multi-step codes, changing the numerical value by 1 results in a newcode word in which several bits are different from the old one. With single-step codes,only one bit changes in the code word in this case.With decadic codes, four bits in each case are grouped together to one decimal digit.The following codes are used:Binary code (multi-step code)Gray code (single-step code)Value range: 00 to FF HexRepetitionUsing the Repetition parameter, you choose whether the data bits in long pulse bundlesare to be repeated every 26 pulses. In this connection, the system automaticallysets the number of data bits to 24.Application: Easy determination of transfer disturbances.Value range: 00 to FF HexTR-ELECTRONIC GmbH, Global Quality Management, Eglishalde 6, 78647 Trossingen, Tel. ++49 (0)7425-228-0, Fax ++49 (0)7425-228-33Date: 10.10.1997 TR - ECE - BA - GB - 0007 - 02 Page 27 of 29

If the fault keeps occurringdespite these measures, you must replace the encoder.Insulating flanges and couplings and cables with twisted-pairwires for data and supply are useful against electrical disturbances.The cable screens should be grounded on bothends. You should only ground the screen on one end in theswitching cabinet if the machine ground has more disturbancescompared to the switching cabinet ground.Plastic couplings prevent mechanical loading of the shaft. Ifthe fault keeps occurring despite these measures, you mustreplace the encoder.If the error occurs when you try to execute the service again,you must replace the encoder.If the error occurs when you try to execute the service again,you must replace the encoder.Set bit 2 30 (read-write bit) to 0.Set bit 2 30 (read-write bit) to 1.Check the executed service number and correct it.Allowed value range:00 FF FF HEX to 1 HEXThe number of steps per revolution must not exceed theencoder resolution stated on the rating place.
